To all wii 'rm it z'riwy concern:

lf-o it known that I, Jos'nrn ll. Fomusr, o oitison of rho United Stan-is, residing: at Glonwood, in the county of Pope and State of Minnesota have invontod curtain now and useful In yrovonionts in (-lriihi-Doors, of which the flowing is ii spooilicstiou.

The prwzont invrntion relates to closures for protoo mg the openings in tho sides of box or grain oars and aims to provide :1, door i prrlorzihlo construction both the main and which may he 'iositivoly and sssily oporiitsd hotl'i to close the opening:- illlil to orzposo tho some as the car is to ho hmdod or unloaded.

The. invention combines with s longitndi holly slida-hlo door n'iouns for positix at-l'y mow the sinus iu'oaoh di'rootion, suoi'i us any; gearing or the stihstnniisl oquivnlout, a polis and a cable or chain.

Tho in volition also oontoniplutos a supple mental door forclosing the. spore show: the main door, said so ipioniontril door lining; mounted ina novel n'iaiinor and supplied with indicating moans ooopm'iitingr with tho main door and door framo to hold it securely when in operative position.

For it full ndorstznnling of tho inwntion and tho mo Lhorool and alsoto ar quirr n knowledge-i of the details of conslriurlimi and the moons ior silo-sting the rosult, ruin-Miro is to ho lnul to tho follonii' description and acoom 'ziniyi'm drawings.

The door may ho applied to any type of box or groin our and inn he (ronstruotodof any suitziblo material oitliorol metal or wood, or a composition of such materials. in the su 'iplonieniiil doors are l'orn'ud of pla to nivt n] of PI'UDQJ' gags and siiliouod and hrzu'od ll) uny'smtul lo nay.

A rini-li liar Cl is also so cured to the door and oxtcnds lengthwise thereof and it Q0221 nhvol =l has its teeth in mosh thoroizith to rllr-d pusitivr' movement of the door in (llllt'l dirrriion upon turning; said groan wheel upon its axis. A shaft 5 mounted in hearings pro ided at one side of the run. has tho gout 4 lost hereto and is adopted to rcruivo :icrunk handle 6 upon its outer end 'hirh pri'ijorls from the sido of the (or a. short distunov for this purposv. A metal pin-to 7 is sorurod to tho up wr sido of tho sill of the our and forms a hruclwt for thedoor 1 to trawl upon. Thi pinto pri'ijerts into l'll( porliot into which lho door slidvs :2, suliiriont distsnocto mm a suppo t for said door. A shroud plate t is sorulvd to tho upper sidv of tho sill lictiu-on the jinnlis of the door l1?lllll! J, and said plate is ol' such ronstrurtion and :u'rnnocnioiu as to have its inner linioitudinol vdgo in u highor plane than tho plain i so us to form a shouhlor l'or tho lower orig n oi tho door to ."hUl against n hon closed. (ind thorvl rvsist fllwniifl upon the inner sido ol' the door to prc-wut out and disphiM-nunt hvlv l. A .oi'iirul hair or pinto H1 is si-wurod to the inner sids of tho door iumb against it lnrii the door (-losos and prox'idos :i. spur-o to rvr-cive the outor 0nd of the door lion rinsed. As shown, the vertical plate 10 has its outer portion oil-sol. and bent to proiido a keeper 11 which is adopted to 0' 'erlap the outer end of the door when closed and confine the same between the inner side of the jamb 12 and the said keeper 11. A guide wheel 13 is located at the upper outer corner of the pocket in which the door 1 slides and is arranged to engage with the upper edge of the door to prevent binding of the same and facilitate the slidin movements of the door when opening and closing the same.

A supplemental door 14 is adapted to close the space above the main door when the latter is closed and is adapted to rest upon the upper edge of said'grain door. A metal strip 15 is secured to the lower edge of the door 14 upon the inner-side and projects a short distance below said edge to overla the upper edge of the main door and there y securing close joint between the two doors, as also to prevent outward movement of the supplemental door when pressure is brought to bear upon the inner side thereof. The supplemental door is of a len th to enable its end portions to engage with t e inner sides of the oor jambs. A rod or bar, 16 is secured at its ends to op osite ends of the door 14 and is spaced a s ort distance from the upper edge of the door to form a guide slot 17 in which a headed fastening 18 secured to the jamb 12 o erates. The rod or bar 16 is bent .at one en to form a vertical loop 19, which admits of the door 14 havin a drop when closed so as to rest upon t e main door.

The loop 19 also forms suspendin means for the inner end of the door when t e latter is open, said 100 being adapted to engage a hook 20 proxi ed upon the inner side of the car near the top thereof to receive the same.

en the supplemental door is closed, its .lower corners engage the confining means of the main door, such as the kee or 11 and the l upper corner portion of the a orementioned pocket. In the modification shown in Figs. 8 and 9, a pulley 21 is fast to the shaft 5 and receiues a chain or cable 22 which is connected at opposite ends to end portions of the door 1, said chain or cable 22 making a turn around said pulley so as to insure sufficient engagement to cause positive sliding movement of the door in each direction upon rotating said shaft in one or the other direction. A tightening device 23 is pro'yided at one end of the chain or cable 22 to take u slack and insure proper engagement of sai -the upper edge of the chain or cable with the pulley. The construction ust described is preferable in some instances to the rack and gear wheel, but is the mechanical equivalent thereof. When the door is closed, it is secured by means ofa pin 24 passed through an opening of said door and adapted to en age with the 'amb at the outer end of the 00 et in which t e door slides. A chain or like connection 25 is fast to the pin and is secured to the car, thereby preventing loss or misplacement of the' pin. To prevent inward displacement of the su plernental door, a clip 26 is attached to tl i e ower edge and overlaps the outer portion of the door 1.

It is desirable to provide for operating the door from the top of the car so that the brakeman may ass from one car to another both to set or re ease the brakes and too en or close the grain door and thereby obviate the necessity of climbing upon and climbing down each car in succession to effect this result. For this purpose, the construction shown in Fig. 10 is )rotided, the same consisting of a vertical s aft 27 mounted in bearings at one side of the car and having a hand wheel at its'upper end and provided at its lower end with a gear wheel 28 in mesh with a gear wheel 29 mounted upon the shaft 5.

Hazing thus described the invention, What is claimed as new is:

In combination with a car having a door 0 ening, a longitudinally slidable door for c osing said opening, a supplemental door adapted to rest upon the main door and provided at its lower edge with a strip to overlap main door upon the inner side, a rod secured at opposlte ends to end portions of the supplemental door and spaced from the upper edge of said supplemental door, and provided at one end with a vertical loop to admit of the door having a drop, a headed fastening applied to a jamb of the door opening and operatin in the space formed between said rod and the upper edge of the supplemental door, and a suspending device to engage with the aforesaid vertical loop to support the door when open.

In testimony whereof I affix my signature in presence of two witnesses.
